David Lehmann owns a vintage trailer, a 1958 Diablo

David Lehmann and wife Soni Bergman don’t actually live in their 1958 Diabl0 trailer nicknamed Rosarita — even though David describes it on his business card as “our little house on wheels.”

“We’ve had it for three years and do take trips with it,” he says while showing his visitors the spiffily-decorated interior. “We took four this year. Each time we have to back it down the driveway by hand.

David, who came to the Bay Area to attend Stanford, is a graphic artist by profession but from a look around his home, it’s clear he’s an artist by avocation. He builds furniture and tree houses and was creating a wind tunnel Christmas present for a friend’s child when we visited.

He works from home, and originally the Diablo trailer was going to be his office, thereby freeing up the spare bedroom for company. “Then we realized the trailer was already a bedroom,” he said. “If we’d converted it to an office, we couldn’t take it on trips!”
